League Of Denial: The NFL, Concussions And The Battle For Truth

"The book should come with a warning label for football fans: Watching a game will never be the same after you read it. The authors tell painful stories of NFL players whose names you may recognize — Mike Webster, Junior Seau, Dave Duerson, to name a few. They introduce you to scientists who fell into researching football-related concussions almost by accident. And they ask tough questions of the NFL, without taking their conclusions too far."
